I've bought this game because I'm also owner of the first blops. I think this is a great game. Especially the multiplayer part. The gameplay in the multiplayer is smooth and quick, no lag. The graphics and the sound are fantastic. There are many modes such as free for all or team deathmatch but also crazy modes such as one bullet. This is a great mode where you have only one bullet and a knife so you have to be carefull when you take a shot. I like this!
The story mode is also ok. I find it a little bit short, but it's intensive and the cutscenes are great. Fantastic graphics.
In short. A must buy!
